Pros: Though it debuted about 10 years ago, technology has only recently improved to make it a viable alternative to the chest strap. But while green light is decent at picking up HR, scientists are leaning more toward red and infrared light for greater accuracy as the wavelengths penetrate the skin better. “When the light reflects off the blood, it’s captured by a sensor and gets processed by an algorithm, along with an accelerometer (measures movement), to produce the HR,” Christle says. By flickering the light hundreds of times per second, wrist-straps can determine how frequently your heart is beating. When your heart beats, the blood flow in your wrist and the light absorption are greater than between beats. How it works: Wrist-worn straps use light-typically green LED lights-and light-sensitive diodes to measure HR in a process known as photoplethysmography (PPG). The lower you put it, the farther away you get from the heart, the higher the chances the signal is going to be poorer,” he says. That makes it difficult for obese people (BMI over 30) and women. “The positioning should be just below the nipple line. “This is the number one option for people who are seriously training,” he adds.Ĭons: Placement is everything. Christle says with confidence that it is the most common, reliable, durable, and affordable of the bunch. Pros: The chest strap has been around the longest (nearly four decades) and is the best studied of all the devices, making it the gold standard. If you’ve put the device on properly, it’s going to get a very good estimation for your heart rate,” Christle explains. That’s the point of contraction of the left ventricle. It’s the big, pointy line going upward in an electrocardiogram (ECG). All you really need here is what we call the R interval. How it works: “Built-in electrodes record the signals of the heart’s electrical connectivity as it pumps blood. Christle, the author of a recent Stanford paper investigating the accuracy of different wearables, to better understand the options. We enlisted the help of exercise physiologist Jeffrey W. Unfortunately, not all HR trackers are created equal. When relying on these measurements to inform your training, accuracy is crucial. While nothing beats paying attention to how you feel during an activity, tracking your heart rate (HR) helps confirm how hard, or little, you worked. Radio frequency/protocol: 2.4 GHz ANT wireless communications protocol BLUETOOTH® Wireless Technology 5.For access to all of our training, gear, and race coverage, plus exclusive training plans, FinisherPix photos, event discounts, and GPS apps,Ī primer on picking your ideal heart rate monitor, depending on your level of data geekiness.Battery life: 12 months (Tri training 1 hour per day).The user-replaceable coin cell battery lasts for up to one year. And don’t worry about running out of juice. Store and Forward Your Data: The device stores heart rate data during swimming or other activities while your watch is out of range, then sends that data to your watch once the activity is finished.Ĭomfort and Convenience: HRM-Pro features a small, lightweight heart rate monitoring module that is no wider than the width of the soft, comfortable strap. That includes metrics such as vertical oscillation, ground contact time, stride length, vertical ratio and more. Track Running Dynamics: In addition to heart rate, HRM-Pro captures running dynamics that can help you improve your form. Heart Rate - the Easy, Accurate Way: This premium heart rate strap transmits real-time heart rate data over ANT+® connectivity and BLUETOOTH® Low Energy technology, giving you more training options. ![]() It can also track running dynamics such as vertical oscillation, ground contact time, stride length, vertical ratio and more so that you can train at your best. HRM-Pro features a small, lightweight heart rate monitoring module that is no wider than the width of the soft, comfortable strap. The user-replaceable coin cell battery lasts for up to one year. If you don't want to connect to a device, it will even store your hear rate data until you come back into range with your watch. It transmits live data over ANT+ and Bluetooth so that it connect to almost any device. The Garmin HRM Pro Heart Rate Monitor is a premium heart rate monitor with Garmin's most advanced technology.
